. BLAsTING-CARTRIDGE SHELL.

Specification of vLetters Patent.

Patented Aug.. 13, 1907.

Application led March 25,1907. Serial No. 364,326.

To all whom it may concern:

Be it known that I, JAMES THOMAS BREWER, a citizen of the United States,residing at Dayton, in the county of Rhea and State ot Tennessee, haveinvented a new and useful Blasting-Cartridge Shell, of which thefollowing is a specification. I

This invention relates to a blasting cartridge shell.

The object of the present invention is to provide a simple, inexpensiveand etlicient blasting cartridge shell, adapted to enable a blastingcartridge to be quickly made;

A further object of the invention is to provide a blasting cartridgeshell, adapted, when filled, to be easily introduced into a hole, andhaving means for enabling a fuse to be readily and securely attached toit.

With these and other objects i`n view, the invention consists in theconstruction and novel combination oi parts hereinafter fully described,illustrated in the accompanying drawing, and pointed out in the claimshereto appended; it being understood that various changes in the form,proportion, size and minor details oi construction, within the scope ofthe claims, may be resorted to without departing from the spirit orsacrificing any of the advantages of the invention.

In the drawing:-Figure l is a side elevation of a blasting cartridgeshell, constructed in accordance with this invention and having the fuseattached. Fig. 2 is a plan view ot the blank from which the shell isconstructed, the clip and the fuse being shown in position. Fig. 3 is adetail sectional view, illustrating lthe manner of securing the fuse tothe shell. Fig. 4 is a detail perspective view of the fuse holding clip.

Like numerals of reference designate corresponding parts in all thelignres of the drawing.

l designates a blasting cartridge shell, constructed of oiled paper, orother damp-proof material, and preferably tapered from top to bottom,and having a lower pointed end 2 to facilitate the introduction ot thecarl tridge into a hole drilled for blasting. The cartridge shell isconstructed ot a single piece of material, thel blank being in the formillustrated in Fig. l, and cut at the bottom to provide two taperedportions 3 and 4. The blank is folded longitudinally on the dotted line5, and the longitudinal edge 6 oi one side oi the blank is folded on thedotted line 7, to provide a longitudinal overlapping iiange or portion.The tapered portion 4 is folded on the dotted llines 8 to provideinclined or angularly disposed overlapping portions or flanges 9 and 10.The overlapping portions or flanges 6, 9, and 10 are secured to theouter faceof the side, on which they are folded by means of glue, orother adhesive material. The shell thus formed is arranged flat beforebeing inflated and a number oiY them may be compactly arranged. Theshell is adapted to be inflated opposite points with tongues 13, taperedto enablethem to readily pierce the shell and bent transversely againstthe exterior of the same, whereby the clip is securely fastened withinthe shell. vided at the other corners with a pair of inwardly extendingfuse-engaging tongues' 14, which in practice may be bent flat againstthe body portion of the clip to enable a number of blasting cartridgeshells to be compactly arranged, and which are adapted to be bentpartially around a fuse, as clearly illustrated in Figs. 2 and 3 of thedrawing. By this construction, a fuse may be readily applied to theshell after the same hasbeen filled with powder. The upper end of theshell is closed by twisting it sharply around the fuse, and whenmaterial is packed upon the cartridge, the upper end of the shell willbe held closed.-

The blasting cartridge shell may be made of any length, and in themaking ot the blasting cartridges, the prepared shells will efect agreat saving in time, over the present mode of construction, commonlyemployed by miners in making cartridges.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent, is:

1. A blasting cartridge shell open at one end and closed at the other,and a clip arranged within the shell near the open end thereof andprovided with means for engaging a fuse. w

2. A blasting cartridge shell constructed of flexible material, saidshell being open at one end and having its other end closed and pointed,and a clip arranged within the shell near the open end thereof andhaving means for engaging a fuse.

3. A blasting cartridge shell provided with an interiorly arranged cliphavingv tongues for securing it to the shell, said clip being alsoprovided with arms arranged to engage a fuse.

4. A blasting cartridge shell formed from a blank havingI oppositetapered portions at one end and foldable longitudinally to bring thetapered portions together, one of the tapered portions being provided atits edges with flanges overlapping and secured to the other taperedportion, and one of the side edges of the blank being provided with anoverlapping longitudinal flange secured to the other side edge.

In testimony, that I claim the foregoing as my own, l have hereto atxedmy signature in the presence of two witnesses. Y

JAMES THOMAS BREWER.
